IMPROVEMENT IN CHEESE-PRESSES.

The Schedule referred to in these Letters Patent and making parl: of the same.

i To all whom it may concern Be it known that I, CHARLES L. Hamas, of North Newburg, in the county of Penobscot and State of Maine, have invented a new and valuable Improvement in Cheese-Presses; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification and to the letters and iigures of reference marked thereon.

Figure 1 of the drawing is a. perspective view of my invention.

My invention relates to cheese-presses, 85o., and consists in the novel arrangement and construction of devices whereby a constant, steady, and powerful pressure is attained at a moderate expense.

A A of the drawing represent two upright standards, of heavy. plank or other suitable material, at a propel' distance, from each other, having the two shelves, b and b', mortised into their inner sides'.

On the lower of these shelves, which is also made of heavy material, the cheese or other article which it is desired to press, is placed.

G represents a top platform or shelf, made of heavy material, placed onthe upper ends ofthe upi'igh ts A A, and extending beyond them at each end,'as shown in the drawing.

About one-third of the distance between the two uprights, en the shelf O, I erect a standard, D, of suitable material, the lower half of which is made in the form of a circular shaft, leaving a shoulder on the standard which rests on the platform C.

'lhc circular shaft a penetrates this platform, passing through the shelf l), under which it is fastened by a nut, rendering it secure and substantial, and Capable of resisting the upward strain of the levers.

To make this upright more secure I attach a brace, f, thereto, one end of which is secured near the top of the standard, and the other near the end ofthe platform or shelf C.

Along the vertical center of this standard I arrange a series of circular holes, it, as shown, the purpose of which is hereafter explained.

Near the other end of the platform C I erect an- `other upright standard G, which, with the exception of the shaft a, is similar in all respects to D, having a series of holes, u n, and brace el.

Through the center of the shelf b and the platform C is passed a movable shaft, E, the lower end vof which is attached either by screw or pin to the collar lof the circular pressing-plate K'.

The upper end of this shaft forms a fork, g, which serves to receive the short lever k.

The body of this lever k is square, tapering toward one end. The other end is formed into a short circular toe, to t the holes it.

The smaller end of the lever is bent upward at right angleslto its length, and the top of this upward bend is concave in form, to receive the long lever R.

One end of this lever lits into the holes n n in the standard G, the other being bent in the form of a hook, as shown, to sustain the weight L.

To render the description of my invention more clear I will explain the operation of pressing any substance, such as cheese, in the press.

The cheese is placed either on the shelf b' or on a block made to receive it, directly under the pressingplate K, which is lowered upon it,then the toe of the short lever le is placed in one of the holes, if, lower than the top of the shaft E, and rests on the fork g.

New, by placing a weight at the opposite end of this lever a pressure equal in proportion to the weight used will be obtained; but to obtain a still greater pressure with the same amount of weight I arrange the short lever, as described, to receive the lever l, one end of which I place in one of the holes, n, lower than the upright part of the lever k, resting the body 0f the lever in the concave face of this bend, and passing it obliquely beyond tbe standard D and to the hooked end attaching the weight L, which, acting upon the two levers, k and It, placed across the rests h and g, gives a powerful .pressure on the object when only a comparatively small weight is employed.

The length of lever necessary to operate with a small weight is, by this arrangement, turned back upon. itself in such a manner as toorcnpy but small space.

vWhat I claim as my invention, and desire to secure by Letters Patent, is-

In combination, the perforated standards D and'G, adjustable combined levers R and It, the follower K, presser-shaft E, and weight L, when constructed and arranged to operate in the manner and for the purposes shown and described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two wit messes.

CHARLES L. HAINES.
